Cideb-mill



A UNITED STATES PATENT OFFICE.'

M. STEVENS, OF LUCAS, OHIO.

CIDER-MILL.

Specification of Letters Patent No. 20,220, dated May 11, 1858.

To all whom it may concern:

Be it known that I, MICHAEL STEVENS, of Lucas, in the county of Richlandand State of Ohio, have invented cert-ain new and useful Improvements inCider-Mills; and I hereby declare the following to be a full and truedescription of the same, reference being had to the drawings herewithpresented, which drawings constitute a part of said description.

The principle of my invention consists in so constructing and arrangingthe several parts of the mill and press or presses as to perform morework with less manual labor than what can be done in mills constructedin the old way.

In order to enable others to make and use my said invention I proceed todescribe the same as follows, see the accompanying drawings.

Figure l is an elevation of the mill and presses having the front boardof the mill removed in order to show the interior arrangement of theparts. (A A,) is the standing part of press and mill. B is the beam. S,S, are the screws. c c are cylinders or rolls being indented so as togear together' and placed so near as that the cog shall come within Jgof an inch of the bottom of the dent, (more or less as required.) Thecogs extend one half the length of the cylinder, and then the cogs onthe other half are placed opposite to the spaces or indentations ofthese. Thus one cog comes to the line of centers while the other on theother half are at the greatest distance giving the same steady motion asit would if twice the number of cogs had been used on the whole length.The advantage of this construction is that it gives large spaces for theapples to enter between the rolls. I do not confine myself to the use ofthis particular form of mill for all purposes but in some cases I use adifferent form of cogs on the cylinder, as for instance where it isconvenient to have a high speed and smaller teeth may be used having aplane or concave back for the apples t0 rest against. The lower part ofthe frame is occupied by the presses. Each press is provided with amovable lining of thin boards or other material so arranged as to beeasily tted in and can readily be taken out while the pulp is in thepress. The object of this is to keep the pulp in its juice for aconsiderable time before pressing it out. It has been found that if theapples are ground and immediately pressed the cider will be pale andwatery but if allowed to steep a few hours, (more or less according totemperature) the liquor dissolves more of the saccharine parts of thefruit and is found to be more rich and finer flavored. This constructionand arrangement of the press is of import-ance in making the finestquality of cider.

Fig. 3 shows the manners of adjusting the lining of the press so as toretain the liquor a sufficient time, and then by loosening the boardsand sliding them upward I take them out and let the pressure on. Eachboard is fitted so as to lap by the edge of the nextin order and ispressed close by the small key or wedge (J, and J,) against its edge.See a top view at Fig. 3.

(D and D) are the sides of the mill (e and e) are two cleavers beinghinged to the bottom of the sides of the mill (D and D) and extendingupward are bent forward so as to hook in to the dents of the cylinders.As the cylinders revolve each cog presses back the cleaver and a spring(d) is placed back of the cleaver and presses it forward. This Cleaveris broad enough to clear the half length of the cylinder and anotherperforms the same office for the other half.

Fig. 2 is a side view of the same having the side D of the mill removedin order to show the cylinders.

Similar letters denote the same parts in the several figures.

It has been common in using the old fashion mill to employ an attendantconstantly to clear the rolls but this device performs that workautomatically and the pulp is then conveyed into the press by thetransferring board F, which being supported on pivots at P can beadjusted either to convey the same to the right or left at pleasure. Bythis means I save all the manual labor of clearing the mill and ofconveying the material to the press. The advantage of having two pressesis in being enabled to keep the mill in constant operation, as one pressIn testimony whereof I hereto set my oarxivk if jil]llingg While theother pressin. naine in presence of tWo Witnesses.
